Wrinkles
Wrinkles are creases, folds and lines in the skin that develop as skin loses collagen, elastin and moisture with age. Sun exposure (photoaging) is the biggest preventable cause, followed by smoking. Repeated facial expressions cause dynamic lines such as crow's feet and frown lines. Daily broad-spectrum sunscreen and not smoking are the most effective prevention. Topical retinoids have the best evidence among creams, while Botox, fillers, chemical peels, lasers and microneedling can soften established wrinkles.
Also called: Rhytides, fine lines, facial lines, crow's feet, frown lines

When to get help
See a doctor within a day or two
- Vision changes, severe pain or skin turning white or blue after a filler injection (possible blocked blood vessel)
- Difficulty swallowing, breathing or speaking, or drooping eyelids spreading after Botox
Book a routine appointment
- A new or changing spot, sore that does not heal, or rough scaly patch in sun-damaged skin (check for skin cancer)
- Rapid, unexplained skin changes, such as thickening or tightening
- Wanting advice on treatment options from a board-certified dermatologist
Usually safe to manage at home
- Gradual fine lines and wrinkles with aging, managed with sun protection and skin care
What causes wrinkles
Intrinsic aging
With time, the skin makes less collagen and elastin, the proteins that give it firmness and stretch. The outer layer thins, oil glands become less active, the fat under the skin decreases and bone structure changes. These changes make skin drier, thinner and less able to spring back.
Sun damage (photoaging)
Ultraviolet (UV) light breaks down collagen and elastin faster than aging alone and is responsible for most visible skin aging on exposed areas such as the face, neck, chest and hands. Photoaging causes:
- deeper, coarser wrinkles
- age spots and uneven color
- rough, leathery texture
- broken blood vessels
- precancerous actinic keratoses and skin cancers
Other causes
- smoking: reduces blood supply and damages collagen; causes vertical lip lines from repeated pursing
- repeated facial expressions: frowning, squinting and smiling create lines that become permanent over time
- sleep position: pressing the face into a pillow
- rosacea and chronic sun-related skin conditions can add redness and texture changes
- rapid weight loss
- genetics and skin type: fair skin shows sun damage earlier
- pollution, poor sleep and dehydration may contribute
Types of wrinkles
| Type | Description | Examples |
|---|---|---|
| Fine lines | Shallow lines, often from dryness or early aging | Under the eyes |
| Dynamic wrinkles | Appear with muscle movement | Crow's feet, forehead lines, frown lines (glabellar lines) |
| Static wrinkles | Visible at rest | Deepened forehead and frown lines |
| Folds | Deeper creases from volume loss and sagging | Nasolabial folds, marionette lines |
Prevention
- Sunscreen every day: broad-spectrum SPF 30 or higher, applied to the face, neck and hands, reapplied every 2 hours outdoors. Studies show daily sunscreen use slows visible skin aging
- seek shade and wear wide-brimmed hats and UV-blocking sunglasses (squinting creates crow's feet)
- avoid tanning beds
- do not smoke
- moisturize to reduce the appearance of fine lines
- eat a balanced diet rich in fruits and vegetables and stay hydrated
- gentle skin care: avoid harsh scrubbing
Treatment
Topical treatments
| Product | Evidence and notes |
|---|---|
| Tretinoin (prescription retinoid) | Strongest evidence; improves fine wrinkles and texture over 3 to 6 months; can cause dryness and irritation; not for use in pregnancy |
| Retinol and retinal (over the counter) | Milder, slower effect; good starting option |
| Tazarotene | Prescription retinoid also used for photoaging |
| Vitamin C serums | Antioxidant; may improve tone and fine lines |
| Alpha hydroxy acids (glycolic, lactic) | Gentle exfoliation; smoother texture |
| Moisturizers and peptides | Temporarily plump skin and reduce fine lines |
Introduce retinoids gradually, two or three nights a week at first, and always use sunscreen, because they increase sun sensitivity.
Procedures
- Botulinum toxin (Botox and similar): relaxes muscles to soften dynamic lines such as frown lines, forehead lines and crow's feet. Effects last 3 to 4 months
- Dermal fillers (hyaluronic acid and others): restore volume in folds and lips; last 6 to 18 months. Rare but serious risks include injection into a blood vessel, which can cause skin death or blindness, so choose an experienced, qualified injector
- Chemical peels: remove damaged outer layers; light peels for fine lines, deeper peels for more significant wrinkles
- Laser resurfacing: ablative (CO2, erbium) and nonablative lasers stimulate collagen; ablative lasers give stronger results with longer recovery
- Microneedling and radiofrequency microneedling: stimulate collagen with tiny needle injuries
- Facelift and other surgery for sagging and deep folds
People with darker skin tones have a higher risk of pigment changes after peels and lasers and should see a dermatologist experienced in treating their skin type.
Frequently asked questions
What causes wrinkles?
Wrinkles are caused by natural aging, which reduces collagen, elastin and fat in the skin, and especially by sun damage, which accelerates collagen breakdown. Smoking, repeated facial expressions and genetics also contribute.
How can I prevent wrinkles?
Use broad-spectrum SPF 30 or higher sunscreen every day, avoid tanning and smoking, wear hats and sunglasses, and moisturize. Starting a topical retinoid can also help prevent and reduce fine lines.
What is the best treatment for wrinkles?
Prescription tretinoin has the strongest evidence among creams. For established wrinkles, botulinum toxin works best for expression lines, fillers for deep folds, and laser resurfacing or chemical peels for overall texture. A dermatologist can recommend the best combination.
Does retinol really reduce wrinkles?
Yes. Retinoids, including over-the-counter retinol and prescription tretinoin, stimulate collagen production and cell turnover, gradually reducing fine wrinkles over 3 to 6 months of regular use. Prescription forms are stronger but more irritating.
Can wrinkles be reversed?
Wrinkles can be softened but not fully reversed. Sun protection and retinoids improve fine lines, and procedures such as Botox, fillers and lasers can make wrinkles much less visible. Results require maintenance.
